Cindy Adams - Believe it or not. Marina Kamen of Kamen Entertainment Group just learned her office was once old-time movie producer Cecil B. DeMille's hidden lair. Nifty hideaway. Secret entrance. The feel of an Arabian sheik's tent. Soaring ceilings, deep sofas, pillars off the "Ben Hur" set. Supposedly starlets came up to discuss their future. Hey, movies are your best entertainment I always say.
